The closet collars 100provide the drain point for a toilet where sewage leaves the toilet andis provided to a sewage system as can be appreciated. The closet collars100 are shown relative to flooring 103. In the embodiment of FIG. 1A,the closet collar 100 is recessed with respect to the flooring 103 sothat the upper surface of the closet collar 100 is flush with thesurface of the flooring 103. Such may occur, for example, where thecloset collar 100 is installed on subflooring and then finished flooring103 is installed around the closet collar 100. For example, ceramic tileor other types of a flooring 103 may be installed on subflooring andresult in the upper surface of the closet collar 100 being flush withthe surface of the flooring 103. Referring to FIG. 1B, shown is asituation in which the closet collar 100 is recessed with respect to theflooring 103 such that the top surface of the closet collar 100 is belowthe top surface of the flooring 103. Such may occur, for example, wherethe closet collar 100 is installed onto subflooring and then finishedflooring having a relatively large thickness is installed around it.With reference to FIG. 1C, shown is a situation in which the closetcollar 100 is installed on top of the flooring 103. In the embodiment ofFIG. 1C, the top surface of the closet collar 100 is above the topsurface of the flooring 103. As contemplated herein, the closet collar100 in any given installation might fall within any one of theconfigurations described with reference to FIG. 1A, 1B, or 1C.

With reference to FIGS. 2A, 2B, and 2C, shown is an example of a closetcollar adapter 113 according to various embodiments. A closet collaradapter 113 includes a pipe extension 116 that is configured to extenddown into a closet collar 100 (FIGS. 1A-1C). Also, a sealing washer 119may be disposed on top of the closet collar adapter 113. According tovarious embodiments, the sealing washer 119 may be affixed to an uppersurface of the closet collar adapter 113 by way of an appropriateadhesive, for example, thereby forming a sealed junction between thesealing washer 119 and the upper surface of the closet collar adapter113. In alternative embodiments, the sealing washer 119 may be affixedto the upper surface of the closet collar adapter 113 by beingovermolded or by using any other suitable process. In furtheralternative embodiments, the sealing washer 119 and the closet collaradapter 113 may be integrally molded as a single part. The sealingwasher 119 may be made from rubber or other appropriate material thatfacilitates an appropriate seal with a horn extending from the undersideof a toilet as will be described.

With reference to FIG. 3, shown is an example of a closet collaradaptation assembly 200 according to various embodiments of the presentdisclosure. According to various embodiments, the closet collaradaptation assembly 200 may include the closet collar adapter 113, aflexible seal ring 203, one or more anchor bolts 206, the sealing washer119, and possibly other components. The closet collar adapter 113 maymount to and form a seal with the closet collar 100. Although theembodiment of FIG. 3 shows the components of the closet collaradaptation assembly 200 as being separate components, in alternativeembodiments, one or more of the components of the adaptation assembly200 may be integrally molded as a single component. In furtheralternative embodiments, one or more of the components of the closetcollar adaptation assembly 200 may be bonded to form a single componentusing, for example, an overmolding process or any other suitable method.

Positioned above the closet collar adaptation assembly 200 is the bottomof a toilet 213 that includes the horn 216. The horn 216 of the toilet213 mates with the closet collar adaptation assembly 200 to form a sealbetween the horn 216 and the closet collar 100. The seal between thehorn 216 and the closet collar adaptation assembly 200 facilitates thepassage of sewage matter from the toilet 213 through the closet collar100 and down the drain pipe as can be appreciated.

The flexible seal ring 203 may be made of a material that facilitatesthe flexible seal ring 203 flexing and at least partially collapsingwith pressure, thereby forming a seal between the underside of thecloset collar adapter 113 and the sealing surface of the closet collar100. In alternative embodiments, a wax ring may be used instead of or inaddition to the flexible seal ring 203. Such a flexible seal ring 203may be made of, for example, neoprene, foam rubber, polyvinylchloride(PVC) rubber, thermoplastic elastomer (TPE), thermoplastic rubber (TPR),styrene-butadiene rubber (SBR), ethylene propylene diene monomer (EPDM)rubber, or any other material that facilitates the flexible seal ring203 at least partially collapsing and sealing against the respectivesurfaces. These materials may facilitate the flexible seal ring 203being reusable, unlike a wax ring which typically is made for a singleuse. In this sense, when the toilet 213 and/or the closet collaradaptation assembly 200 is removed, the flexible seal ring 203 mayreturn at least partially to the shape in which it was prior to thetoilet 213 and/or the closet collar adaptation assembly 200 causing theflexible seal ring 203 to at least partially collapse. Additionally, theflexible seal ring 203 may comprise an antimicrobial material. Forexample, the flexible seal ring 203 may comprise an antimicrobialcoating.

The sealing washer 119 may thereby form a sealwith the sides of the horn 216 to prevent sewage gases or other matterfrom escaping during the toilet flush cycle or at other times. Theanchor bolts 206 may be restricted to the closet collar 100 in holes orslots that are typically found within closet collars 100 as can beappreciated.

With reference to FIG. 5, shown is an example of the closet collaradaptation assembly 200 in which the toilet 213 has been placed over thecloset collar adaptation assembly 200 and the horn 216 has been pressedthrough the center opening of the sealing washer 119. As shown, thesealing washer 119 may be stretched down around the sides of the horn216, thereby forming a seal between the side of the horn 216 and thesealing washer 119. In addition, wax may be provided at strategiclocations inside the closet collar adapter 113 so that the sides of thehorn 216 may come into contact with the wax to form a seal in additionto, or as an alternative to, the use of the sealing washer 119. Forexample, such wax may be placed in the corner 223 or in other locationsformed in the closet collar adapter 113. As a result, the wax maycontact a portion of the horn 216 to further form a seal between thehorn 216 and closet collar adapter 113. In alternative embodiments, theside walls of the closet collar adapter 113 may be shaped to provide forholding areas or reservoirs in which wax or other sealants may beretained. When the horn 216 is inserted into closet collar adapter 113,the wax or other sealants in the holding areas or reservoirs may comeinto contact with the horn 216. The holding areas or reservoirs mayprovide for greater precision in terms of sealing to prevent sewageleaks and may also facilitate assembly and/or installation of the closetcollar adaptation assembly 200.
